The trcsess utility consolidates trace output from selected trace files based on several criteria: trcsess &nbsp[output=output_file_name]         &nbsp[session=session_id]         &nbsp[clientid=client_id]         &nbsp[service=service_name]         &nbsp[action=action_name]         &nbsp[module=module_name]         &nbsp[trace_files] trcsess output=main.trc service=psdwh *trc After the consolidate trace file had been generated you can execute tkprof on it. For example: tkprof main.trc main.prf sys=no sort=exeela TKPROF: Release 10.2.0.3.0 - Production on Thu Feb 28 13:38:23 2008 Copyright (c) 1982, 2005, Oracle.

In my firm we have a seperation between System guys to the DBAs, we don't have root privileges. this is the reason that they are peparing us the ASM disks. After using "/etc/init.d/oracleasm createdisk..." I tailored a script to see all the information that I can get WITHOUT the need to connect to the ASM instance. #!/bin/ksh export ORACLE_HOME=`grep ASM /etc/oratab | cut -d: -f2` export PATH=$PATH:~$user/dba/scripts/bin:$ORACLE_HOME/bin export SID=`grep ASM /etc/oratab | cut -d: -f1` printf "\n%-15s %-14s %-11s %s\n" "ASM disk" "based on" "Minor,Major" "Size (Mb)" printf "%-15s %-14s %-11s %s\n" "===============" "=============" "===========" "=========" for i in `/etc/init.d/oracleasm listdisks` do v_asmdisk=`/etc/init.d/oracleasm querydisk $i | awk '{print $2}' | sed 's/\"//g'` v_minor=`/etc/init.d/oracleasm querydisk $i | awk -F[ '{print $2}'
